Receive Highway Bit Offset[2
0].
RBITOFF is used to offset the beginning
of an incoming frame by the indicated number of bit times. If no bit offsets are
required, these bits should be set to 000. The following list shows the effect of
setting these bits.
000 = no bit offset
001 = 1-bit offset
010 = 2-bit offset
. . .
111 = 7-bit offset
Note:
Bit periods are relative to the highway data rate set for each highway.
RTSOFF, RBITOFF, and RFBOFF are used in conjunction to define the start of
the incoming frame. The values are added together to position the sampling of
time slot 0, bit 0 for each highway.
Receive Highway Fractional Bit Offset[1
0].
RFBOFF is used to offset the
beginning of an incoming frame by the indicated number of fractional bit times.
If no fractional bit offsets are required, these bits should be set to 00. The fol-
lowing list shows the effect of these bits.

RFBOFF

00 = no fractional bit offset
01 = 1/4-bit fractional offset
10 = 1/2-bit fractional offset
11 = 3/4-bit fractional offset
Note:
Bit periods are relative to the highway data rate set for each highway.
RTSOFF, RBITOFF, and RFBOFF are used in conjunction to define the start of
the incoming frame. The values are added together to position the sampling of
time slot 0, bit 0 for each highway.
